Hi all. I just want to confirm a theory here. I'm looking at NTA and seeing that switching my Top XX Applications between Netflow and NBAR2 shows vastly different data in terms of numbers, i.e., the total amount of data in GB that's passed through an interface. Am I correct in assuming that NBAR2 will not identify as much…
I've recently installed a trial version of Network Traffic Analyzer (NTA) and I want to get this configured and working so that I can make a case to my senior colleagues and manager to purchase it as I think it would benefit us greatly. The problem I'm having is that I can't get NBAR2 working even though our core switch…
I've received notifications in Orion that our company has nbar2 capable devices which are not sending nbar2 data. I was tasked with testing this out to see if we like it better than netflow. I have the flow record, monitor and exporter configured how the solarwinds documentation shows but I don't see the data coming into…
I've got this concept floating around in my head... I'd love to see this made possible. jpetkevich and I discussed it briefly at Cisco Live this year, I'm curious how others might use this feature. So here's the idea... instead of running compliance/remediation against a full-blown running/startup config, what if NCM…
If you haven't enabled NBAR2 in your routers, you're not getting all that Netflow offers. You're missing the Application data that's passing through your L3 interfaces. And you're probably getting Alerts from NTA, telling you that it's receiving Netflow data that's missing NBAR2 information from an NBAR2-compatible device.…
This is showing NetFlow and Nbar2 details. Same Interface, same time-frame. All I did was flip the Dropdown at the Top Right from NetFlow to NBar2 to show how much more detail you can see with NBar2. PURPOSE: Showing how NBar2 can be configured, using the NBar2 Protocol Pack to see more details as to the sites used. Add…
I've got some new Cisco Nexus 7710 with brandnew NX-OS 8.0(1) which i want to use as cores for my access-layer. Today i've tried to get nbar working but i can't find the relevant commands. I found this on cisco page: Enabling Protocol Discovery on an Interface Perform this task to enable protocol discovery on an interface.…
Hi, I would like to request NTA support for the Cisco 3k series device latest flow enhancement. With the latest enhancement it is possible to export NBAR based flow data from the f.ex 3650/3850 devices. NTA should support following flow fields: match ipv4 version match ipv4 protocol match application name match connection…
Can anyone point me in the right direction to a change template that will allow me to update an existing router config for netflow to add NBAR2? I basically need to achieve the following (any help greatly appreciated) 1. Remove the active flow record so it can be amended., using a wildcard from interface description or…
Understanding network bandwidth content is one of the essentials for each IT admin who needs to ensure the business traffic has always the priority over someones private Youtube streaming during a lunch break. SolarWinds Network Traffic Analyzer has been used many years for its ability to finger point at IP address which…
